Centos7 安装搭建 Discuz3.4 论坛
1.安装 php 环境
查看 PHP 是否已经安装
[root@ppl ~]# pwd
/root
[root@ppl ~]# yum list installed | grep php
[root@ppl ~]#
安装 PHP 吧，这里装的是 PHP7.1 版本
这个清理工作命令，不一定用的上。但是为了防止您的 centos 上面发生 php 冲突，所以，这个命令还是先执行一下更好些。
yum -y remove php*
1、安装 epel-release
输入指令：yum -y install epel-release
[root@ppl ~]# yum -y install epel-release

epel-release.noarch 0:7-11
Complete!
[root@ppl ~]#
回车等待安装成功.
2、安装 PHP7.0
1.首先我们先来获取 PHP7.1 的 yum 源，执行下面的指令：
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
php 高版本的 yum 源地址，有两部分，其中一部分是 epel-release，另外一部分来自 webtatic。如果跳过 epel-release 的话，安装 webtatic 的时候，会有错误爆出。
执行过程如下：
[root@ppl ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Retrieving https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

[root@ppl ~]#
获取成功后我们可通过下面的指令来查看 php7.1 的扩展名称，可以按照自己的要求安装
2.查看扩展名指令：yum search php71w 或者 yum -y install php72w
[root@ppl ~]# yum search php71w

[root@ppl ~]#
4.安装成功了，我来查看以下是否安装成功了，输入下面的指令看出版本试试吧！
指令：php -v
能看到下图的内容就证明安装成功了！
[root@ppl ~]# php -v
PHP 7.1.24 (cli) (built: Nov 11 2018 08:03:49) ( NTS )
Copyright (c) 1997-2018 The PHP Group

[root@ppl ~]#
5.(选做)安装完成之后，#whereis php 可以看到 php 的安装目录，然后我们来给 php 配置环境,实际上在 centos7 上 php.ini 已经不用像在 Windows 上那样配置了。我们只需要修改这个文件的参数设置 cgi.fix_pathinfo，默认设置值为“1”，用；进行注释或修改为 0 即可。
2.PHP 启动
这个 php-fpm.service 文件，位于下述路径中：/lib/systemd/system/ 中。在这个目录下面，可以看到相关的开机服务项目。
systemctl status php-fpm.service //查看PHP运行状态
systemctl start php-fpm.service //启动PHP
systemctl stop php-fpm.service //停止PHP
systemctl restart php-fpm.service //重启PHP
systemctl reload php-fpm.service //重启修改配置
//开机启动
systemctl enable php-fpm.service
systemctl start php-fpm.service
开启 fpm 服务，就基本上大功告成了。
查看PHP状态
[root@ppl ~]# systemctl status php-fpm.service
● php-fpm.service - The PHP FastCGI Process Manager
Loaded: loaded (/usr/lib/systemd/system/php-fpm.service; disabled; vendor preset: disabled)

[root@ppl html]#
PHP 的监听端口配置
more /etc/php-fpm.d/www.confimage
3.上传 discuz 安装包
1.建立目录
#建立目录，也可以直接部署到html目录中
mkdir /usr/local/nginx/html/bbs
将 Discuz_X3.4_SC_UTF8.zip 解压 （SC 为简体中文版），并将其中 upload 目录下的所有文件上传到前面建立的 BBS 中。
使用-R 参数可实现递归功能，即所有子目录中的文件与目录均拷贝 $ cp -R 源目录/* 目地目录
[root@ppl dir_SC_UTF8]# ll -h
total 4.0K
drwxr-xr-x 2 root root 102 Dec 29 2017 readme
drwxr-xr-x 13 root root 4.0K Dec 29 2017 upload
drwxr-xr-x 4 root root 94 Dec 29 2017 utility
[root@ppl dir_SC_UTF8]# cp -R upload/* /usr/local/nginx/html/bbs
2.修改目录权限
[root@ppl bbs]# cd ../
[root@ppl html]# chmod -R 777 bbs/
[root@ppl html]# ll -h
total 12K
-rw-r--r-- 1 root root 537 Nov 23 03:57 50x.html
drwxrwxrwx 13 root root 4.0K Dec 18 05:12 bbs
-rw-r--r-- 1 root root 612 Nov 23 03:57 index.html
3.配置 Nginx
#
location ~ \.php$ {
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html/bbs$fastcgi_script_name;
}
4.进入 nginx 目录并启动
[root@ppl conf]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@ppl conf]#
//启动
[root@ppl nginx-1.14.0]# cd /usr/local/nginx
[root@ppl nginx]# pwd
/usr/local/nginx
[root@ppl nginx]# /usr/local/nginx/sbin/nginx
或者
./nginx -c /usr/local/nginx/conf/nginx.conf
//查看Nginx启动状态
[root@ppl sbin]# ps -ef | grep nginx
root 7098 1 0 05:36 ? 00:00:00 nginx: master process ./nginx -c /usr/local/nginx/conf/nginx.conf
nobody 7099 7098 0 05:36 ? 00:00:00 nginx: worker process
root 7121 5777 0 05:36 pts/1 00:00:00 grep --color=auto nginx
[root@ppl sbin]#
4.浏览器打开安装
http://192.168.153.100/install
安装完毕后，记得一定要删除 install 目录或者删除 install 下面的 index.php。
重命名即可
cd /usr/local/nginx/html/bbs
mv install install.bak
或者
rm -rf ./install
5.扩展
为了让 apache 支持 php7.2，需要修改 apache 的配置文件：
首先，找到 php 的配置文件：php.ini，利用 find 命令：
find / -name php.ini
通常情况下位于/etc 中，也就是/etc/php.ini。
然后找到 apache 的配置文件：httpd.conf
find / -name httpd.conf
然后修改该文件，在该文件最后一行加上：
PHPIniDir /etc/php.ini
表示告诉 apache，php 的配置信息文件。
